Cinema is the fancy word for film. A cinematographer is the person who sets up a shot - including angle and the amount of feet and inches everything is from the lens of the camera. In america when people go see a movie they say "Let's go see a movie". If they are interested in plays then they say "Let's go to the theatre". People who shoot video are called videographers. Lately though, some are starting to call themselves cinematographers even though they are shooting video.
